HOT-WATER RESERVOIR FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 715,666, dated December1902- 'Applioation filed September 23, 1901. Serial No 76,256. (Nomodel.)

To all whom it may concern:

Be it known that 1, WILLIAM J. KEEP, a citizen f the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Hot-Water Reservoirs for Stoves;and I declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to hot-Water reservoirs for stoves and the meansemployed to r 5 attach the reservoir to the stove.

It has for its object an improved hot-water reservoir arranged to beattached to cooking stoves or ranges, and especially adapted tosheet-steel cooking stoves or ranges, in which the thinness of thematerial of the sides renders them readily flexible, the especial objectbeing to provide such a means for attachment that the reservoir can beattached or detached easily and conveniently and make a tight joint andwithout the use of tools. The stove or range is provided with an openingat the rear with which the reservoir engages and through which openingthe hot gases from the stove pass and impinge directly against the wallsof the reservoir.

In the drawings, Figure 1 is a sectional elevation showing the rear ofthe stove and the reservoir. Fig. 2 is a horizontal cross-section at theline a a of Fig. 1. Fig. 3 is a plan view showing the top of thereservoir and the top of the rear part of the stove. Fig. 4. is aperspective of the damper.

A indicates the rear wall of the stove.

B indicates the rear wall of the oven.

0 indicates the reservoir, which is made with upright practicallyvertical rear wall and end walls a l) c, with a horizontal bottom (1. Tothe bottom 01 of the reservoirv is secured a plate 6, which projectshorizontally forward and is bent along its front edge,

which engages at the back of the range with a double bend f, forming agroove, the mouth of which is turned downward, and the projection eengages over the upper edge of the rear side A of the range, with therear wall of the range engaging in the groove in the bend f. The sidepieces D D close the end openings between the rear of the range and thereservoir, and these side pieces are Socured to the reservoir, and eachterminates at its front vertical edges E With a scroll-like bend thatforms a short vertical split tube, which is preferably rectangular incross-section rather than round in cross-section. The projecting rearends of the side pieces of the range are bent to form correspondingsplit tubes G G, and the bend of the one part engages closely in thebend of the other part, the parts being brought into engagement bylifting the reservoir until the loweriends of the tubes g g are abovethe upper ends of the tubes G G, engaging the ends of the one tube inthe end of the other tube and forcing the reservoir down until thegroove in the bent extension e engages over the rear wall of the range.I do not confine myself to these exact joints, but to any joints whichwill accomplish the same purpose. When in this position, the top of thereservoir engages against the top of the range with a projecting part ofthe plate K engaging over a flange m, that projects from the top of therange, and the two parts are held together by turn-buttons T. The stemof each button T engages through a hole in the plate which forms the 8oframe of the reservoir and engages also through an elongated slot in theflange m, and on the bottom of the stem is a button, which engages underthe flange 'm. Some other similar clamping device may be used. Thereservoir may be easily engaged or dis-' engaged from the body of therange, and the engagement is made without using cement and without theuse of tools. The joint is tight and secure. go

A damper or valve 2, with projecting arms 3 4, is pivoted near thebottom of the chamber 5 and is swung by a lever 6 to a position with itstop resting either against the reservoir or against the back of the ovenand across the descending flue, which leads directly from the fire.There is an opening between the arms 3 and 4 and the plate of the damperthat furnishes a passage for gases when the damper is turned forward,and the damper deflects the gases from the reservoir, protecting thereservoir from them when the damper is turned back.

This invention is applicable to ranges having a single flue between theoven and the reservoir or to stoves or ranges having two or three fines.In the latter case the fluestrips K, only one of which is shown in theconstruction illustrated by the drawings, dividing the flues, areprovided on their rear vertical edges with grooves, and a strip on thefront of the reservoir is provided to engage such grooves. The edge ofthe strip which is attached to the reservoir, which edge lies againstthe reservoir, is curved to press against the reservoir-wall, so thatwhen the edge of said strip comes against the grooved edge of thefine-strip K it will do so with a yielding pressure and a tight jointwill be formed between the two edges.

What I claim is 1. The combination of a range having an opening boundedby three edges one of which is approximately at right angles to theother two and a sheet-metal reservoir having the metal at its edges bentto engage the bounding edges of said opening so as to develop theresiliency of the sheet metal of said reservoir to hold the jointstight.

2. The combination of a range having an opening bounded by three edgesone of which is approximately at right angles to the other two, asheet-metal reservoir having the metal at its edges bent to engage thebounding edges of said opening so as to develop the resiliency of thesheet metal of said reservoir to hold the joints tight, a flange topprovided with means for engaging the reservoir-top and turn-buttons orsimilar devices arranged to secure the range and reservoir together tohold the joints in engagement.

3. A strip upon the reservoir having one of its edges curved so as topress against the flexible side of said reservoir, said strip beingadapted at its other edge to contact the edge of the flue-strip so as toform a yielding engagement therewith.

4. A damper 2, provided with projecting arms 3 and 4, pivoted near thebottom of a reservoir that can be swung against the oven and deflect theheat against the side of the reservoir and against the reservoir todeflect the heat away from the reservoir, substantially as described.

5. In combination with a range, a reservoir with projecting Wallsextending from the reservoir-body toward the range whereby there isformed a chamber outside the range, a damper pivoted at the bottom ofsaid chamber having an opening at its lower part, and means for turningsaid damper against the reservoir or against the oven.

6. In combination with a range provided with a descending fluecommunicating directly with the fire, a reservoir with Walls forming achamber adjacent to said flue, a damper affording an opening at itslower part pivoted at the bottom of said chamber and extending upward,said damper being adapted to swing against the reservoir, or across saidflue.

In testimony whereof I sign this specification in the presence of twowitnesses.

WVILLIAM J. KEEP.
